Li2O2, also known as lithium peroxide, is a chemical compound consisting of two lithium atoms and two oxygen atoms. In English, it is called Lithium peroxide. The molar mass of Li2O2 is 45.88 g/mol. Its molecular structure includes two lithium atoms and two oxygen atoms, with each oxygen atom linked to two lithium atoms.
Li2O2 is solid, white, and odorless. Its pH level has not been clearly determined due to its unique properties.
Chemically, Li2O2 can react strongly with water and acid, producing hydrogen peroxide and corresponding lithium salts.
Common chemical equations of Li2O2 include:
Li2O2 does not directly react with metals or nonmetals, and it also does not react with salts.
The preparation of Li2O2 in the laboratory and industry both rely on the reaction between lithium and oxygen, although the specific conditions of the reaction may vary. An example of a reaction to prepare Li2O2 is:
However, due to the strong properties of Li2O2, its preparation and handling require carefulness and strict adherence to safety regulations.
